California’s Democratic incumbents face primary challenges from political newcomers
WASHINGTON — In Napa and surrounding counties, Rep. Mike Thompson’s once-easy reelection contest is turning into something of a race. In the Sacramento area, Rep. Doris Matsui is facing one of her most serious challengers in two decades. In Los Angeles, a former White House climate official wants to unseat Rep. Brad Sherman.
In these districts and others, newcomers are challenging some of the most recognizable Democratic names in California politics in the June 2 primary election.
The challenges are part of a national wave reshaping the debate over generational power and the direction of the Democratic Party ahead of the 2026 midterms, when party leaders hope to retake control of the House. They reflect — and capitalize on — restlessness among progressive voters frustrated with the status quo, worried about affordability and looking for fresh leadership.
The question of when elder lawmakers should step aside has dogged both parties for years, from the late-career health scares of senators including Republican Mitch McConnell and Democrat Dianne Feinstein to the generational debates sparked by progressive figures such as Rep. Alexandria Ocasio-Cortez and New York City Mayor Zohran Mamdani.
The debate reached a critical moment for Democrats in 2024, when President Biden withdrew from his reelection campaign under pressure over his age and mental acuity. In California, Rep. Nancy Pelosi, 86, has chosen to retire at the end of her current term.

Now, a handful of California’s primary contests have revived a predictable debate: Some in the party see the argument that lawmakers in their 70s and 80s should step aside as ageist and naive; others argue Democrats need to allow for generational turnover, particularly after the party’s 2024 failure to beat President Trump.
“The Democratic Party has not been delivering, and the power structure there is crumbling,” said Eric Jones, 35, an entrepreneur who is challenging Thompson in the newly redrawn 4th District. “Where’s the hope? Where’s the dreaming? Where’s the future? I don’t see any of that coming out of this current political class.”
Incumbents argue that trading experience for a fresh face is a false promise. In statements to The Times, several pointed to their legislative accomplishments. “Now is not the time for on-the-job training,” said Thomas Dowling, a spokesperson for Thompson.
The redistricting created by Proposition 50 has helped open the door to newcomer candidates in the 4th and 7th districts, where Thompson and Matsui are facing challengers, making those races more competitive. Both districts were redrawn so that the incumbents must earn the trust of new voters who have never before seen them on their ballots.
“They’re still Democratic, but some of the voters are different,” said Christian Grose, a professor of political science and public policy at USC. “I think that has created an opportunity for a couple of those younger people up north, where districts have changed.”
The two races differ — Thompson, for instance, has received endorsements from young-voter groups, such as the Sacramento County Young Democrats, and at 75, is younger than Matsui, 81.
Matsui, meanwhile, is favored in fundraising, with roughly $1 million in cash to the $315,000 brought in by challenger Mai Vang, a Sacramento City Council member backed by progressive groups who has cast her campaign as one fueled by working families and criticized Matsui for relying on corporate donors. Jones’ challenge has forced Thompson to match his fundraising and door-knocking efforts — both candidates have raised roughly $3 million, their campaigns said.
“Others think being a leader is screaming and shouting,” Matsui told The Times. “I think it is about being effective.”

A broader pattern emerges
California is home to three of the 13 members of Congress age 80 or older who are seeking reelection in 2026 — Matsui; Rep. Maxine Waters, 87; and Rep. John Garamendi, 81. All three are facing their first serious primary challenges in years.
“It’s going to take new types of energy, new thoughts, and leadership, to fight what is happening in our country right now,” said Myla Rahman, 53, a Los Angeles Democrat in the 43rd District challenging Waters, who has held the seat for 35 years.
The primary election will also feature a handful of open contests in solidly blue districts where long-standing incumbents are stepping aside — including Pelosi’s San Francisco seat and retiring Rep. Julia Brownley’s Ventura County district — offering newcomers their first real opening in years.
In Alameda County, a primary election is set for June 16 for the seat vacated by former Rep. Eric Swalwell, who resigned last month amid sexual assault accusations.
National Democrats, meanwhile, are focused on defending incumbents in two swing districts in California that the party considers crucial to winning the House majority: Rep. Derek Tran of Orange County, who won his seat by just over 600 votes in 2024, and Rep. Adam Gray of the Central Valley, who faces a competitive field.
In both competitive partisan races and in Democrat-on-Democrat contests, analysts say frustration about the economy is bubbling up from voters.
A statewide survey released in February by the Public Policy Institute of California found that 56% of likely voters believe a candidate’s position on affordability was very important in determining their vote in a House race — yet only 20% said they approve of the job Congress is doing.
Among voters under 35, the numbers were starker: 76% named cost of living a top concern, and just 13% approved of Congress.
Those numbers help explain why young voters may be looking for new options from primary challengers, said Mark Baldassare, president and chief executive of the Public Policy Institute of California. Much of the disillusionment stems from economic pressures, he said.
“If you’re getting a 13% approval rating in Congress among 18- to 34-year-olds, that tells you a lot about how people are feeling about the status quo,” Baldassare said.
The trend reflects a mix of younger candidates who have grown tired of waiting their turn, others who are driven by ideology, and others who simply see a rare opening against a vulnerable incumbent, Grose said.
“If you’re a savvy young candidate, it may be easier to beat an incumbent who is over 80 than to then primary 20 people when the person retires later on,” he said.
The challenge for challengers
Still, newcomers face a steep climb against opponents whose names are well known in communities where they have been deeply embedded over the years.
Rahman, a nonprofit director, acknowledged it’s challenging to run against someone like Waters, who is nationally known and has voter loyalty. But she said the cost of groceries, gas and housing have people questioning whether their representatives in Congress are doing enough.
In Solano County, Garamendi, who has served in Congress since 2009 and held senior posts in state government since the 1970s, faces three challengers — two Democrats and one Republican — in the redrawn 8th District.
“Experience matters, both when you’re fighting Trump and when you’re working to improve our community,” he said when he launched his reelection bid.
In Los Angeles’ 32nd District, Sherman, 71, is attempting to fend off Jake Levine, 41, a former Obama and Biden White House climate aide who decided to run after losing his childhood home in the Palisades fire.
“For 30 years, we’ve been told that seniority equals effectiveness, and that time in office equals progress,” Levine said. “But people across our district — who are contending with $7 gas and housing prices driving people out of L.A. — can feel that’s not true.”
Sherman, who has been in Congress since 1997, dismissed the generational-change argument bluntly.
“If you have never shown that you can stand up to the other side in a tough legislative debate, then you might as well just go out there and say, ‘I’ve never done anything, I’ve never proven I can do anything, but I am new,’” Sherman said.
